Solutions and Mixtures
Homogeneous Mixture
A homogeneous mixture is a mixture that has a uniform composition throughout. Such a
mixture is called a homogeneous mixture.
Heterogeneous Mixture
A heterogeneous mixture contains physically distinct parts and has a non-uniform
composition. Such mixtures are called heterogeneous mixtures.
Examples: Mixture of sodium chloride and iron filings, salt and sulphur, oil and water.
What is a Solution?
A solution is a homogeneous mixture of two or more substances. Examples: Lemonade, soda
water, etc., are all examples of solutions.
Solid solution: Alloys
Gaseous solution: Air
Components of a Solution
A solution has two components — solute and solvent.
• The component present in a large amount is called the solvent.
• The component of the solution that dissolves in the solvent is called the solute (present in
lesser quantity).
Example: A solution of sugar in water is a solid in liquid solution. In this solution, sugar is
the solute and water is the solvent.
